Of all the oceans, |
| [00:01.56] |
the Pacific is by far the largest, |
| [00:03.97] |
stretching almost a third of the way round the globe. |
| [00:07.05] |
It's so huge that the current in the South Pacific takes several years to complete just one cycle. |
| [00:13.46] |
In an ocean this vast, many animals have to travel huge distances to survive. |
| [00:19.10] |
None more so than the sperm whale, one of the greatest voyagers on the planet. |
| [00:24.65] |
Every year, |
| [00:25.44] |
thousands of bull sperm whales, |
| [00:27.71] |
some from as far as Antarctica, |
| [00:29.85] |
come to the tropics to breed. |
| [00:32.43] |
After 15 years away, |
| [00:34.46] |
fattening themselves up in colder climes, |
| [00:37.17] |
they are now back and big enough to compete for a mate. |
| [00:40.93] |
These warm, |
| [00:41.87] |
equatorial waters make ideal nurseries. |
| [00:45.38] |
At just a week old, |
| [00:46.93] |
this white calf already weighs over a tonne. |
| [00:49.65] |
For the next six years he will stay by his mother's side, |
| [00:53.20] |
relaxing in these tropical waters where killer whales,his only natural predator,are rarely found. |
| [00:59.75] |
But it was in these peaceful stretches of ocean that, |
| [01:03.14] |
200 years ago, whales met whalemen. |
